How can I efficiently remove elements from the end of an array in Vue.js?

Is there a way to splice data starting from the back with a higher index?

When clicking on the .delete div, how can I make it so the .image-box div deletes starting from the end?

I need help implementing this feature in my code. Here is a snippet:

<div class = "image-cover">
    <div class = "image-box"  v-for = "(image, index) in images" :key = "image.id" >
        <div class = "index">{{ index }}</div>
        <img :src = "image.url" class = "previewImage"/>
    </div>
</div>
<div class = "delete" @click="deleteImage" v-on:click  = "delete image in here!">-</div>

Answer №1

If my understanding is correct, you are looking to remove the last elements (highest index) first?

If that's the case, you can simply use images.length to retrieve the last index:

images.splice(images.length - 1, 1); // remove the last image

If you need to remove multiple elements, subtract (1 + numberToRemove) from images.length:

images.splice(images.length - 4, 3); // remove the last 3 elements

or:

const numToRemove = 3;
images.splice(images.length - 1 - numToRemove, numToRemove);
